Product Overview

The ATMEGA48P-20PU is a high-performance picoPower 8-bit AVR RISC-based Microcontroller combines 4kB ISP flash memory with read-while-write capabilities, 256byte EEPROM, 512byte SRAM, 23 general purpose I/O lines, 32 general purpose working registers, three flexible timers/counters with compare modes, internal and external interrupts, serial programmable USART, a byte-oriented 2-wire serial interface, SPI serial port, 6-channel 10-bit A/D converter, programmable watchdog timer with internal oscillator and five software selectable power saving modes. The device operates between 2.7 to 5.5V. By executing powerful instructions in a single clock cycle, the device achieves throughputs approaching 1MIPS per MHz, balancing power consumption and processing speed. The device is manufactured using Atmel's high density non-volatile memory technology. The on-chip ISP flash allows the program memory to be reprogrammed in-system through an SPI serial interface.
  • Advanced RISC architecture
  • Power-on reset and programmable brown-out detection
  • Internal calibrated RC oscillator
  • External and internal interrupt sources
  • Six sleep modes - idle, ADC noise reduction, power-save, power-down, standby and extended standby
  • 131 powerful instructions-most single clock cycle execution
  • 32 x 8 general purpose working registers
  • Fully static operation
  • Up to 20MIPS throughput at 20MHz
  • On-chip 2-cycle multiplier
  • QTouch® library support
  • Programmable watchdog timer with separate on-chip oscillator
  • On-chip analogue comparator
  • Interrupt and wake-up on pin change
  • Two 8-bit timers/counters with separate prescalers and compare modes
  • One 16 bit timer/counter with separate prescaler, compare mode and capture mode
  • Real-time counter with separate oscillator
  • Six PWM channels
  • Programmable serial USART
  • Serial peripheral interface (SPI)
